STRANGENESS #1: In ToA I'm at war with the Dregnin and have been for some time, taking their planets one by one.
I go into Iconian territory where the Dregs have a starbase and attack it. A window pops up warning me that by attacking the starbase I will start a war with the Dregs!!!
As gramps used to say, WTF?
STRANGENESS #2: Since I want to wipe out that Dreg SB and since I'm already at war with them, I go ahead and attack.
Then a window pops up telling me that the rule that everyone must wait a week after declaring war before attacking must be obeyed. Clearly the game refuses to recognize my war with the Dregs has been going on for many weeks. So I waited a week and blew away the SB.
This strangeness doesn't break the game but it does make me wonder what other odd things are lurking.
